Physics - NLM Question with Solution | TestHub

From the graph we can say, upto $\mathrm{t}=2.0\mathrm{s}$, the body moves with a constant velocity Slope of position-time graph $=\frac{4}{2}=2\mathrm{m}/\mathrm{s}$ After $\mathrm{t}=2.0\mathrm{s}$, position-time graph is parallel to time axis i.e., body comes to rest. $\therefore$ Change in velocity $=\mathrm{dx}=2\mathrm{m}/\mathrm{s}$ Impulse $=$ Change in momentum $=\mathrm{mdv}=0.1\times 2=0.2\mathrm{kg}\mathrm{m}/\mathrm{s}$
